Speccaton forming part of Letters Patent No. 8,120, dated June 3, 1913; Reissued December- 27,

In the accompanying'drawing, Figure l,

is a top view of my burring and cleaning machine, and Fig. 2, a vertical section there-. of, from front to back, through the middle.

a, a, are the ordinary feed rollers, around one of which an endless apron, not represented in the drawing, is to pass, in the usual manner; Z2, b, is the picker cylinder which takes the wool, &c., from the feed apron, as in other machines for a like purpose; c, is a toothed, or saw, cylinder thatk takes the burs, &c., from the material as it is carried around on the fine-comb cylinder; d, is a cylinder which I denominate the receiver; which receiver, and thetoothed or saw cylinder, constitute in their manner of combination with the other parts, the most important features of my new machine. e, e, is the fine-comb cylinder; f, is the fan, or cleaning, cylinder; these two last, and the first, or picker, cylinder, not differing from those before in use.

In using this machine, the cylinders are to move in the direction indicated by the arrows. For a machine of ordinary size, the picker. cylinder may be about eighteen inches in diameter; the receiver about twelve inches; the fine-comb cylinder about two feet; the toothed or saw cylinder about siX inches; the fan about twelve inches. The cylinders may be driven by bands and whirls, in the ordinary way, and their relative velocities should beV nearly as follows: The fine-comb cylinder may have about three hundred, or three hundred and twenty ive revolutions in a minute; the picker cylinder may perform two revolutions on its aXis to one of the fine-comb cylinder; the receiver may make one revolution to two of the inecomb cylinder; the same may be the case with the toothed, or saw, cylinder; the fan may revolve four times to each revolution of the ne-comb cylinder. Should the relative diameters of any of the cylinders be vciselythe same with those above indicated,

changed, their angular velocities are to be varied in a corresponding degree; for although it is not necessary thattheir peripheries should revolve with velocities prefthe proper action ofthe machine will depend, in a considerable degree, upon the relative speed of the respective operating surfaces. .Y n f The wool, or cotton, placed upon the feeding apron, is takentherefrom by the picker cylinder, as heretofore, and from this it is" taken by the .teeth on the cylinder that I have denominated the receiver, which cylinder, as aboveremarked, constitutes a new feature in itscombination ywith the burringV and cleaning machine. vThe teeth upon the receiver are hooked, and may consist of strongrcard teeth; these teeth carry the wool,- or cotton, Vtothe fine comb cylinder; and byV the employment of said cylinder the fiber is spread with much more evenness upon the Y, ne-comb ,cylinderv than has been attained under any arrangement heretofore adopted,r There may be two, or more, such receivers, 1; if preferred, placed one above the' other,. each of them running the same way,`andj performing av like oice. The wool, or cot ton, may in this case be vspread thinner upon each of them, andthe work be still per-gA formed with equal rapidity; an increasef'in the number ofrreceivers will be found particularly advantageous with some kinds of wool and cotton. v

The toothed cylinder 0, kI make in theffol-V i. i lowing manner: I take the required number t of circular saws of the 'proper diameter, i and these I place upon a shaft, interposing; L disks of wood, or other substance, of about,V an4 eighth of an inch. in thickness, between; f them; thus Vforming a ./cylind'er. of; sawsf similarto that used in the saw gin for cot-j ton, only with the saw plates nearerto each; other. The teeth of this cylinder takethe I burs, seeds, or other foreign matter, -from i I the wool, or cotton, on the Vline-comb cylin-, der, andV throw them toward the picker; and by the rapid motionkoflsaidcylinder/theyV are beaten down, and fall underV the ma; chine; this beating down ofV theburs, v&o., isi not sensibly interfered with by the` small.` quantity Of'wool on the-teeth ofthe picke cylinder. In all the machines f heretofore t employed for the burring und cleaning of Wool, much of lthe fiber has been broken by the instruments employed for the separation; this inconvenience and loss are completely obviated by the combining of the toothed, or saw, cylinder, constructed as above described, With the fine-comb cylinder. A casing of sheet metal, or other material, g, g, extends under the fine-comb cylinder, but has an opening' which admits the action of the receiver upon said line-comb cylinder; this casing-prevents any portion of the burs from being carried back to the point of action between these tWo cylinders. The construction and action of the fan, or cleaning' cylinder, are the same as in some other machines for u like purpose.

Having' thus fully described the manner in which I construct my improved burring and cleaning' machine, and shown the manner in Which the same operates, what I claim therein as new, und desire to secure by Letters Patent, 1s

l. The combining' if u cylinder such as I` have denominated the toothed, or saw, cylinder, With the fine comb cylinder of a burring, cleaning, or ginning, machine, in the manner and for the purpose set forth; I do not claim the constructing of such a cylin-` under the name of a receiver, With the pickerv and 'fine-comb cylinder, so as to operate betweenthem, in the manner, and for the puljpose, herein made known.
